Abstract: The invention relates to a process for the preparation of methyl formate by reacting methanol with carbon monoxide at a pressure of from 0.5 to 10 MPa abs. and a temperature of from 50 to 150° C. in the presence of a metal alkoxide as catalyst in a reactor, in which a gas stream is withdrawn from the reactor, entrained methyl formate is removed from this gas stream by condensation, and all or some of the remaining gas stream is returned to the reactor as circulating-gas stream and a mean gas superficial velocity of from 1 to 20 cm/s is set in at least one region of the reactor in which the gas flows essentially in one direction.

Abstract: A process is described for preparing acid formates in which methyl formate is reacted with water and a basic compound having a pK a of the conjugate acid of the corresponding dissociation state of >=3 measured at 25° C. in aqueous solution, the methanol formed is separated off and, optionally, the desired acid content is set by adding formic acid.

Abstract: A process for qualitatively or quantitatively detecting a fuel additive component which is part of an analyte comprising a fuel and/or further fuel additive components, by contacting the analyte with an indicator and determining the change, caused by the interaction between fuel additive component and indicator, in the color properties of the indicator in the analyte.
